Ok guys i have a 338RUM XCR with a badger 20moa base mark 4 rings and a 6.5 x 20 lupe LR 50mm with varmit rec. a Dillion 550 press so i want to go to sportsman warehouse this morning and get started i will go with 225NAB now i need to buy dies once! whats the best ! and what powder should i use and can you tell me what case prep i should do thanks this round will be used on antelope to moose at 50yds to 800 to 900 i know i will have to slow down the loads for under 100yd opportunities
First off - I am by no means an expert, so hopefully some of them will chime in a help out a bit.
that being said, I too, have used a dillion 550, using it i found that i really ended up using it one stage at a time and most importantly I hand measured the powder charge for each and every load for my 300RUM. I, too, like redding dies, i bought full length dies. the way i do it with my dillion 550 is to take preped brass, then lube that cases, size the case and put a new primer in, all in the first station. then i take the brass and add a hand measured powder charge. then once all the cases are full of powder i take them back to the press and put one in at a time and put them trough the next die to place the bullet.
I don't think the powder charge on the 550 is anywhere near accurate enough for a magnum rifle, so plan on using a scale. I can't really help with specific powders or loads for the 338 but do a search, there is tons of info here.
yes all powder charges will be hand weighed and for big rifle i use the dillion like a single stage all though i would like to finally get a electronic powder dispenser and weight rig thanks for the imput I will get the Redding comp dies and regular resizing die the other thing i need is a good case trimmer any suggestions thanks oh one more thing is hand primer better then just letting the the press do it thanks
I use the RCBS hand primer and the trimmer from Sinclair....think it is a Wilson. It is the one where you place the case inside the bushing, makes for the most uniform trimming as the case is not held with a pilot in the mouth.
